CLINTON C. MURPHY, DECEASED, LATE OF CHICAGO, ILLINOIS; BY EDNA BLANKE MURPHY, ADMINISTRATRIX, MURPHY, OF NEW YORK, N. Y.

1 0 all whom it may concern:

Be it known that CLINTON C. MURPHY, deceased,- late a. citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, did invent certain new and useful Improvements in Car Doors, of which the following is a full, clear, and exact description.

This invention relates to improvements in car doors, and particularly to the sliding car doors set forth in a copending application for Letters Patent of the United States filed July 18, 1918, Serial No. 244,698, of which this application is a division.

The object of this invention is to hold the door tightly against the side of the car when shut and .to seal the edges thereof so that rain and dust cannot-find their way around the same into the car. This is accomplished by the means hereinafter fully described, and as particularly pointed out in the claims.

In the drawings:

Figure 1 is a side view of a portion of a freight car, including the sliding door,

showing my improvements applied thereto.

Figure 2 show an enlarged view of the lower left hand corner of the door.

Figure 3 is a similar view of the upper left hand corner of the same. s

Figure 4 is a vertical section taken on dotted line k4, Figure 1.

Figure 5 is-a horizontal view taken on dotted line 55, Figure 1, drawn to an enlarged scale.

Figure 6 is a transverse section of the lower left hand corner of the door, taken on dotted line 6 6, Figure 2.

Referring to the drawings, 6 represents the sheathing of the car side; 7 the doorframe and 8 a sliding door for closing the doorway. The edges of the door are bound by metal strips a, b, 0 and d, and at the corners are protected bytruncated triangular shaped corner-plates A, B, C and D which constitute continuations of the pro tection provided for the edges of the door by said strips as-well as reinforcing said corners. The lower edge of the door is protected by a special rolled metal shoe-strip a which, between the lower corner-plates C and D is substantially Z-shaped in cross section. The horizontal portion of this shoe- Serial No. 297,535.

the upper vertical flange of the same laps tecting the rear edge is angle shaped in cross-section, and one wing thereof laps against the rear margin of the door, and the other wing bears against the rear edge ofthe same and is of such width that its inner edge 6' extends beyond the inner side of said door andthe projecting 'portionor inner edge 6 is bent towardthe rear post of the door-frame 9. The door-frame 7 projec'ts out beyondthe vertical plane of the outer surface of the side of the car, and the projecting portion f the rear side of the rea -post of the door-frame has a vertically disposed angle-iron 10 bolted or otherwise secured thereto, one flange of which projects to the rear flush with the outer edgeof the door. l/Vhen the door is closed inner edge 7) engages angle-ironlO and thus not only I draws the dOOr closely against the doorpost, but seals the joint between the same.

The vertical strip a protecting the forward edge" of the door is Z-shaped in crosssection and its'outer flangeis secured to the outer'margin of the said forward edge; its inner flange projects forward from said edge flush with the vertical plane of the inner side of the "door and its web connect ing these'flanges engages and protects the front edge of thesame. i

The upper edge of the door is also'pro tected. The metal strip d employed for this purpose is substantially S-shaped in crosssection; its lower flange laps against the upper outer marginal surface of the door; its horizontal web protects and engages the upper edge of the door, and the structure thereof projecting above the door forms a hori zoutal runway theopen side of WhlCh faces outwards.

plates. The vertical and horizontal edges of plates A and B aline with the webs of strips 0 and d that protect the forward and top edges of the door and with the webs of strips 7) and (Z protecting the rear and top edges of the same, and these vertical and horizontal edges are flanged inwards and protect the adjacent vertical and horizontal edges of the door. The angles of these corner-plates A and B formed by the meeting of the vertical horizontal and hypotenuse edges thereof are truncated, and the ends of the binding strip (Z of the door, and the upper ends of the binding strips 6 and 0 thereof engage any may form a butt joint with said truncated angles, but I prefer to extend the ends of these strips under said plates and to inortise them at the corners.

The lower corners of the door are each provided with corner-plates C and D, respectively, that are preferably, made of cast metal the angles at the ends of the hypotenuse edge being truncated. These plates have their vertical and horizontal edge portions built outwards to form ridges, the inner sides of which are grooved for the reception of the ends of the strip a and the lower ends of the vertical edge strips Z) and o, of The area or web bound by these ridges and the hypotenuse edge of said plates is depressed and comes in direct contact with the outer surface of the door, and the outer edges of said strips are flanged inwards and lap against and protect the adjacent edges of the door at its corners.

The vertical flanged edge of the forward corner-plate C is angle-shaped in cross-section, and corresponds in dimensions to the similar portion of the vertical Z-shaped door-strip e and constitutes a continuation of the same.

lVhen the car door is closed the flange of strip projecting forward therefrom passes back of the outer flange of a vertical Z- shaped metal jainb-strip 11 that is secured to the outer edge of the door-post of door- This strip 11 has its inner flange secured in a rabbetted portion of the outer surface of the door post and the outer flange projects toward the door and is held out from said surface so as to provide a vertical channel into which the forwardly projecting flange of the door enters when the latter is closed. The jancb or stop strip 11 is braced against the thrust of the door by brack ets 1-1.

' Above the upper edge of the door asubstantially S-sbaped horizontally disposed overhead metal strip 12 is placed the upper flange of which is secured to the fascia of the car, and the portion below said upper flange projects outwards, then downwards and then inwards to form a channel or runway, the open side of which faces inwards. The cross-section of this strip 12 corresponds to that of door-strip d for the top of the door, and the upper outwardly projecting horizontal flange of strip (Z enters the runway of strip 12 and interlocks with and travels longitudinally in the same.

Strip 1? extends from a point at or adjacent to the upper left hand corner of the doorway distance corresponding to the length of the door plus the length of its movement. The upper lefthand corner of said doorway is covered and protected by a triangular shaped shield or corner pocket E. The vertical and horizontal edges of this shield aline with the upper edges of the overhead strip 12, and the vertical edge of jainb-strip 11 farthest from the doorway. The marginal portions of the shield adjacent these edges are secured to the outer surfaces of the upper flange of the overhead-strip and the flange of the jamb-strip secured to the door-post and the portion bound by these edges and the hypotenuse edge thereof is raised or stands out from the plane of its vertical and horizontal margins a distance sufficient to cover over the outer flanges of said strips and so that the corner ofthe door covered by plate A can enter behind it when said door is closed and be held against the side of the car thereby and protected and shielded so that dust and rain cannot enter the car around said corners.

If desired, the shield could be re-enforced by casting a bead g integral with its hypotenuse edge; providing its outer srface with a diagonal fin 71, extending from the center of length of its hypotenuse edge toward the angle of its vertical and horizontal edges, and providing integral braces k, in, connecting said edges with the sides of the raised part of the shield.
